Question
In a school election between two nominees 'P' and 'Q',
12% of the total votes were considered invalid. If 'P' secured 60% of the valid votes and 'Q' received 21,120 valid votes, calculate the total number of votes polled.Solution
ATQ,
Let the total number of votes be '100n'
Number of valid votes = 0.88 × 100n = 88n
Number of valid votes received by 'Q' = 0.40 × 88n = 35.2n
So, 35.2n = 21,120
Or, n = 600
Therefore, total number of votes = 600 × 100 = 60,000
